SHAFT BEARING.

Application filed January 3, 1921. Serial No. 434,462.

To all whom it may concewt:

Be it known that I, JOHN I. GUETL, a

citizen of the United States, residin at Buffalo, in the county of Erie and tate of New York, have invented new and useful Improvements in Shaftv Bearings, of which the following is a specification.

This invention relates to a self-oiling:

shaft-bearing of the type shown and described in Letters Patent of the .United States No. 1,178,231, dated April 4, 1916..

In this patent, the shaft is provided with collars which elevate the oil from the oilwell of the bearing-box to the upper side of the shaft, and one or more saddles which straddle said collars and serve to deflect the oil laterally andspread it over the top of the shaft. If the base of such a saddle is too close to the shaft, the oil is liable to overflow the bearing, while if the saddle is raised too far above the shaft too much oil,

escapes under the saddle and the top of the 1 shaft'is insufliciently lubricated. To obtain the best results with such a saddle, exactness of construction and nicety of adjustment are The object of my present invention is the provision of a saddle of this kind which while insuring proper lubrication of the shaft and guarding against overflowing, is

not dependent for its successful operation upon'refinement of construction and: adjustment, but permits a certaindegree of coarseness without detracting from its efliciency, thus reducing the cost of the device and requiring no special care in applying it to the bearing.

In the accompanying drawings: Figure 1 is a longitudinal central section of a bearing provided with the improvement. Figure 2 is a transverse section thereof on line 2-2,.

Fig. 1. Figure 3 is an enlarged perspective view of the saddle.

Similar characters of reference indicate corresponding parts throughout the several views.

10 indicates the bearing boxhaving the customary babbitted seat 11 for the shaft 12. The shaft carries the. oil-elevating collars or flanges 13 which dip into the oil wells 14 arranged at opposite ends of the shaft-seat 11 and connected by the usual channel 11*. These collars extend through slots 15 and 16 in the top and bottom of the shaft seat, the upper portions of the collars projecting into the usual covered filling and inspectionopenings 17 infthe top v if of the bearing box.

. Arranged within said filling openings and straddling the adjacent portions of the shaft-collars are the saddles or oil deflectors 18. Each of these saddles consists ofa plate,

somewhat narrower than the filling opening, having in its lower edge a central notch. 19

which receives the. companion collar and snugly fits the same to prevent leakage-0f oil between'thesel'parts. As in the saddleof the patent hereinbefore mentioned, the

edge of the saddle notch is preferably bounded by a flange 20 whichprojects be-* yond the face of the saddle-andterminates at its lower ends-in feet 2,1,the toesior frontportionsof which rest upon the shaft 12.

The undersides of these' feet are preferably horizontal, or substantially so, asshown, to bring the lower edge of the saddle in close proximity to the shaft.

Above the notch 19, the saddle is pro-. Vided with an oil relief-passage oropening 22 which extends through the saddle plate and is preferably formed partly in a boss or upward extension 23 of the saddle-flange 20'.

This opening may be tapered. toward the passage of the oil through it.

In practice, each of the saddles rests against the" rear wall of the corresponding filling opening 17 with its relief-passage 22 located belowsaid wall and within theomain i hamber of the bearing box, as shown in [back of the saddle, as shown,'to. retard thev uring the rotation of the shaft, its coli larsi13 which turn in the direction of-the arrow in Fig. 2, elevate the oil in the usual I I manner. A portion of the oil, encountering the saddle-flange 20 and the body, of the saddle, is deflected laterally and passes I I around the sides. of the saddle and returns, into one of the wells 14, while another porj tion of theelevated 'oil passes through the relief passage 22 of the, saddle and, flows back'into the well.

' By this improved construction of'the saddle, its base may be placed closely enough I to the top of the shaft to properly retard the flow of the oil and insurethorough lubrication of that partoftheshaft, while the relief passage allowsthe surplus oilto escape through it, effectually guarding against overflowing of the bearing-box. This relief opening permits of a more or lessinexact construction and fitting of the saddle without sacrifice in the efficiency 17 reliability boxes cemprising a plate haying in its, lower of the lubricating devices; and it. follows e g EL 110K111 f0 e ing an oilreflevating that less time, and care are required to prodeviee, and provided in its side between said 10 d th ddl d it i correspondnotch end the upper edge of the plate with 5 i l d d a relief-passage extending through the plate.

I claim as my invention: An oil distributing saddle for beating JOHN I. GUETL.
